A group of three girls were sitting, giddily, in a semicircle around the “boy” they’d invited to their secret hideout - which may or may not have just been a small furnished playhouse in one of the girls’ parents’ backyard.
Manny, a little Siamese cat of eight years, sat in a girly pink tank top and denim short-shorts. Taylor, a chubbier seven-year-old Bombay with all black fur, sat in a hand-me-down blouse and pink washed jeans - both of which she’d received from her sister. Manny. The smallest of the group was Samantha, a Birman kitten. Barely five years old, she was wearing a teensy sun dress and absolutely nothing else.
“I do announce,” the oldest girl in the circle, Manny, proudly declared with her most authoritative voice possible, “that this meeting of the Cutie Kitties Anti-Cooties Club is begun!”
“Hear hear!” The youngest girl in the circle, Samantha, replied.
“Today’s official business!” Manny continued. “We are taking in a new member in the fight against cooties. A convert from the boys’ side of the war!”
“Wait,” Taylor chimed in, “is that even possible? Don’t boys all have cooties, and we’re trying to not-”
“Yes, boys all have cooties, but she’s not a boy anymore!” Manny cut her sister off.
Jamie, the single “boy” in the club, squirmed in his seat. He was hardly dressed like a girl, wearing a loose fitting t-shirt and some cheap shorts. Totally average, generic “boy” clothes. But in his hair sat a little dandelion crown the girls had woven just for him to signify that he was one of them now.
“Y-Yeah!” Jamie added, mustering up all the courage he feasibly could. “I don’t wanna be a boy anymore. Boys are gross.”
“Hear hear!” Samantha added to his assessment. 
“Exactly! And to join the ranks of the Cutie Kitties Anti-Cooties Club, he is renouncing his boyhood once and for all!” Manny proudly declared.
“What does “renouncing” mean?” Taylor asked, though Manny didn’t reply.
“You have three tasks you must complete!” Manny continued. “Each, a gruelling test of your spirit to wash away every last trace of boy from you!”
Jamie swallowed nervously, but the mixed-breed nine-year-old kitty nodded his assent to the tests. “I’m ready, Manny! I won’t be a boy before the day is out!” 
Taylor giggled in excitement. “Perfect! Can I go first, Manny?”
Manny proudly held up her finger. “First! You will perform Taylor’s test of the spirit! Taylor?”
Taylor got up, giggling, and went to the slightly-weathered dresser at the back of the house. She opened up the top drawer, lifted a few makeup supplies out of the way, and pulled free a red dress, covered with sequins. It looked a bit too long for her, and a bit too thin. 
“As your first test, Jamie! You will... get butt naked for us, and put on your special girl dress! It’s extra girly, to cancel out any of the extra boy in you!”
Jamie’s heart fluttered as he looked at the beautiful dress. He imagined how it would feel on his skin, against his fur. How it would hug his every part, just like the beautiful gowns and dresses he’d seen in Cinderella, Beauty and the Beast, and Who Framed Roger Rabbit. Just the thought of it made a funny feeling he didn’t understand well up in his chest, which migrated down to his privates.
“Wait, naked?” Jamie trepidatiously asked.
“NAKED!” Samantha yelled. “No boy clothes anymore! At all! They’re gross and full of cooties!”
He shivered and hesitated, but after a moment, he made a decision that would change the course of his life for good. He got up off the floor, gently took his dandelion wreath off, and pulled off his shirt.
Samantha, Manny, and Taylor gasped as he bared his chest to them.
With only some hesitation, Jamie hooked his fingers into the waistband of his shorts, gave them a quick tug, and pulled both shorts and underwear off in one fell swoop. The discarded clothes dropped into a pile, which he summarily kicked away from him.
All three of the other cats watched him in shock and surprise. Though none of them would admit it, all of them were staring exactly where any immature little girl would look - straight at his penis. His pillar of “manhood” between his legs. The part of the body that, at their age, truly separated boys from girls.
The cold breeze between his cheeks and on his little shaft made that funny feeling he felt in his private parts return, and with just a few quick heartbeats, his kitten shaft was already throbbing and pulsing erect.
All three kitties watching stared on in awe. In awe of him. In awe of his shaft. In awe of how his penis was somehow getting bigger. And as the three other girls’ faces blushed deeper and deeper, Jamie started thrashing his tail about.
“C-Could I please put on the dress?” He finally mustered up the courage to ask.
“Uh...” Taylor whimpered softly as she stared at his cute little cub dick.
“Nnnnnot before you put the wreath back on!” Samantha spoke up, breaking the spell that seeing a “boy’s” privates had put on the trio. “The wreath is the only thing keeping us from getting cooties until the tasks are complete!”
Jamie didn’t hesitate. He bent down, picked up the little crown of dandelions, and placed it back on his head, right between his ears.
Somehow, having just the wreath on, he felt far, far more naked than he did moments before. And the feeling of nakedness had only made his little penis pulse ever the more erect. Now, his kitten shaft stood and pulsed freely in the open air of the clubhouse, proudly announcing the seven-incher’s presence.
“Wow!” Samantha purred. “You’re almost as big as my daddy!”
“Are... Are all... boy... parts... uh, like that?” Manny whispered.
“N-No! They’re... Sometimes smaller, and sometimes bigger!” Jamie fussed.
“It was smaller, then it got bigger!” Taylor remarked. “Why did it do that?”
“Boy parts grow when they’re happy and excited!” Samantha helpfully clarified. “That’s why my daddy’s boy parts get big when I sit on his lap, because he’s happy to see me!”
Taylor, for her part, did at the least stop staring long enough to carry the dress over to Jamie, who eagerly donned the beautiful garment.
As he slipped it on over his shoulders and Taylor helped him pull it down, all of his expectations about how it should feel were proven true. It clung to his skin, accentuated his body, felt oh-so right, and... did absolutely nothing to conceal how huge, horny, and throbbing his erection was.
“Uh...” Taylor whispered. She’d crouched down to help pull his dress on, and now was staring that cute little cub cock right in the face. The sequinned dress was doing very little to conceal every inch of the shaft from her.
“R-Right, you’ve accomplished your first task!” Manny did her very best to conceal the growing ball of feelings in her belly. Feelings she didn’t understand, but... kind of liked. A lot. “You’re one step closer to being a girl now!”
“Hear hear!” Samantha chimed in. Her parents’ promiscuity helped her not be so confused about everything happening with Jamie’s body.
“Your, um, second task! You... Have to... Put on makeup!” Manny picked herself up off the ground and pried her eyes away from Jamie’s tented skirt.
“Uhm... Not much makeup, right? I don’t want to have to wash my fur too much later...” Jamie whimpered. Anything to get the attention off of his huge throbbing cub boner, which Taylor remained eye-level with.
“We’ll be the judge of that!” Samantha yelled. Volume control was not her strongest suit yet. “Taylor, stop looking at his peepee already!”
“S-Sorry!” Taylor pried herself away from his thighs and gave a halfhearted, blushing smile.
Jamie shuffled awkwardly over to the dresser where the makeup was kept. Once there, Manny sat him down, pulled his chin up, and had him stare at himself in the mirror. 
“Okay, now close your eyes.”
Jamie obliged, and he shut his eyes. By now, his heart was pounding and his belly was full of butterflies and he couldn’t stop the way his penis was throbbing and pulsing between his thighs. His head was in a rush, and he couldn’t formulate a single coherent thought. He didn’t know how to explain the myriad feelings in his chest, how it ranged from want to happy to scared and more. And every emotion was so strong that he couldn’t think about them; just feel them. Not that an average nine-year-old like him could understand emotional intelligence.
“Okay, now open.” 
What felt like merely seconds had passed, and Jamie opened his eyes. He looked in the mirror and... staring back at him was the cutest, sweetest, most heart-poundingly precious and beautiful girl in the world. She had beautiful eyeliner, thick lashes, the slightest, sweetest blush to her cheeks, a cherry red lip tint, and a few matching hair extensions clipped in. There was no “boy” left in her, just a beautiful girl. The most beautiful girl he’d ever seen.
Jamie had no words.
“Do you like it?” Manny asked, almost rhetorically.
Jamie had no words. His eyes teared up slightly.
“Is that a yes?”
As his vision went watery, and the realization sank in that the girl in the mirror staring back was really her, she sniffled. Then nodded.
“Great!” Manny smiled. She was clearly less moved by what she was seeing than Jamie, but she wasn’t the one seeing herself how she’d only dreamed of being for the first time.
“And for your final task!” Samantha shouted. “You have to give up your old name, and pick a new one! And, and you have to seal it with a kiss!”
“Wait, with a kiss?” Taylor hissed. “Sammy that wasn’t what we’d said.”
“Changed my mind, she needs to kiss us!”
“Bull-butt, you changed your mind! You can’t just do that!” 
As the two little girls bickered, Manny looked down at the teary-eyed Jamie.
“You okay, Jamie?” She asked.
“C-Can you... Can you please call me “Ellie” in- instead?” 
Manny smiled warmly at the brand-new girl she’d just helped make. 
“Of course I can, Ellie!” She pulled the bottom of her shirt up and blotted at the tears in Ellie’s eyes, to make sure not to disturb the makeup she’d carefully just applied.
“- well I don’t care I’m not going to make out with h- oh, what’d you say?” Taylor looked up at Manny. Her black tail was bristling with agitation.
“Congratulations, girls, we now have our newest member of the Cutie Kitties Anti-Cooties Club! Say hello to...” Manny spun the chair around, showing the blubbering, grinning girl. “... Ellie!”
“Ellie!” Taylor beamed at her. “You look so pretty, Ellie! Oh my gosh, how do you feel?”
“No, no! She’s not done yet!” Samantha interrupted before Ellie could respond. “She has to kiss us!”
Manny groaned and looked over at the kitten. “Ugh. No, Sammy. I’m not kissing her.”
“Whuh, but- but- but- but you have to! It’s part of the task!” 
Taylor and Manny both just shook their heads. Ellie, as a growing blush spread over her face, just looked down at the little girl with a borderline unreadable expression from the tears of joy in her eyes.
“Well, poo to you, I’m gonna kiss her! Cuz if we don’t, the girl part might not stay, and she might go back to being a boy! Then we’ll have a boy in the club, and we can’t have that!”
“Sammy, if she did, we would just kick her out-” Taylor was interrupted by Samantha’s stubborn insistence.
Without a counter-argument, the teensy kitten stood up, grumpily stomped over to Ellie, hopped up on her lap, and put her hands on her shoulders. She locked eyes with the newest addition to the club, and subtly rocked her hips back and forth along Ellie’s still-pounding boner.
“Ellie. Do you promise, from now and until forever, to never again go back to being a boy? Do you promise?”
Ellie, blearily, smirked. Her candy-red lips invited kissing, and Samantha was so close to being in kissing-range…
“I p-promise!” Ellie whimpered, adopting her best rendition of a proper girly voice. 
“Good! We can help you stop talking like a boy later. Congratulations, you’re a girl now!”
Samantha leaned forward, shut her eyes, and christened the girl with a kiss.
At first, it was a simple, innocent kiss. Just two girls, four years apart, holding mouths against each other. Two girls, four years apart, with their privates separated by two thin dresses. After they held the kiss for five straight seconds, and Ellie’s pounding heartbeat and funny feelings in her crotch had reached the strongest they’d ever been, a soft whimper for more from the older girl spurred a different set of funny feelings from the five-year-old. 
Samantha tilted her head to the side a bit, opened her mouth, and sloppily French-kissed Ellie. Her immature lack of practice and imitation of things she’d seen on TV and her parents doing as her only guides meant it was far from pristine, but the sensation of tongue licking Ellie’s lips spurred her heart and set the butterflies in her stomach to new, fluttery highs.
She reciprocated Samantha’s beginner frenching. The tween and the tyke’s tongues started sloppily slurping against each other, and the hem of the pretty dress Ellie was wearing gradually got dragged further and further upwards as her erection pulsed and Samantha’s legs tugged at it. In practically no time at all, her sundress had a bare girldick pushing against the edge of it.
Samantha’s mouth had gone sloppy and red from the cherry-flavoured lipstick smearing everywhere, and Ellie’s lips had suffered a similar treatment as their drooling, oozing saliva had spread it around her face. But even as her makeup smudged and her mascara ran, Ellie only redoubled her effort into Samantha’s kiss.
While still holding Ellie’s tongue in her mouth, Samantha stood up a little bit, hiked up her sundress, and sat back down, pushing the bare lips of her five-year-old snatch against the tip of Ellie’s nine-year-old penis. Samantha whimpered and whined in delight and bliss as her lips were spread by rubbing against Ellie’s too-large head.
The two sisters watching this display were positively enthralled. Enraptured. It was their first exposure to true, sloppy, messy love. To the very concept of two girls sharing love. To lust, and to arousal. It left them both utterly sticky between the thighs, frozen in place, and unable to do anything but stare, mouth agape, at the show of debauchery from the youngest and oldest members of their club.
Without even sharing a word, Samantha reached under her dress, finagled Ellie’s penis-tip right up against the tip of her teensy tot twat, and ground her hot, warm, inviting entrance against it. A warm, sloppy, and unprepared act of underage lust.
As the kitten’s hands touched Ellie’s throbbing, hyper-stimulated privates, she started a chain reaction in her. Something neither had ever done before. Ellie’s child prostate throbbed, and her pulsating, quivering shaft tensed, and her very first ever orgasm rippled through her body. A strange sensation; one she couldn’t place. It felt so right, so perfect, so weird and tingly and exciting and amazing and a hundred other words. And it felt so, so different from when she had to pee. In that moment, she put her trust in Samantha that she knew what she was doing, and let the tyke push her own private parts down right onto the head.
Samantha’s itty bitty kitty cunny spasmed and throbbed with a million weird feelings, itself, but none as weird as the feeling of what she was internally thinking of as ‘private part kissing’. As her own act of kissing was already so sloppy and wet, she didn’t think anything of it when Ellie’s penis suddenly ejaculated for the first time, causing thick and gooey nearly-clear off-white strands of barely-active sperm to spurt from the child’s shaft. As she’d just pushed down and only the first quarter-inch of Ellie’s tip had managed to peek right inside her labia, all those fluids spurted right straight into her body to gunk up her vagina.
The two rode out their first kiss and Ellie’s first orgasm in bliss together, though Ellie’s sudden twitching, moaning, whining, and spasming was a bit concerning to the sisters spectating. As soon as her penis had stopped spewing gooey stuff into Samantha’s little pussy, Samantha broke the kiss, and the two prepubescent lovers panted in bliss, connected orally by strands of makeup and saliva and physically by Samantha’s little cunny spreading as wide as it feasibly could to accommodate Ellie’s overgrown privates.
Samantha, finally, offered a big, toothy, innocent grin at Ellie.
“There! You’re a girl now! You’ll never ever be a boy again!”
Ellie, whose brain was still effectively mush, just whined in bliss and let out a giddy, girlish giggle. 
Samantha pulled back, slid off Ellie’s lap, and flopped onto the floor. She sat back, hiked up her skirt, and stared down at her little creampie.
“Hey, Ellie, look! You put drool in my private parts, too!” She giggled, then reached down and started fingering herself idly; cramming Ellie’s cum back into her snatch.
“Wh- What… was that?” Ellie shuddered. Her dick had only gone slightly soft, and it was now bending down a bit.
“Kissing, I think. I dunno! That’s just something daddy and I did a bit, then mommy got mad at him and he stopped. It’s really fun, right?”
“Yeah!” Ellie agreed. “That’s… That’s the best, oh my gosh! Kissing is the best!”
Manny, who was following Samantha’s lead and was now touching her privates through her shorts, coughed. 
“Um, Ellie… Is it too late to say I changed my mind…? I… I wanna kiss you too, since… since you’re a girl.” Manny struggled to find the right words to say.
“Can we, um, try doing the thing Sammy just did, too? With our privates?” Ellie asked.
Manny just nodded, and she undid the fly on her shorts. As soon as they were down, she started pulling her panties off, and her cub pussy’s juices stuck to her panties as she peeled her mound free.
“Uh, how about, we… Samantha, how did you usually kiss?” Ellie asked. “Like, sitting on my lap, or what?”
“I once saw mommy and daddy kissing while on the table, so maybe try lying down and doing it that way?” Samantha shrugged. She’d pulled some of Ellie’s cum from her pussy and was examining it in only the way a 5 year old could - staring, sniffing, and licking it. 
Manny quickly pushed some of the stuff off of the picnic table in the clubhouse, laid back, and spread her legs near the edge of it. She propped herself up with her elbows to look down at Ellie, waiting for her to take her initiative.
“Uhm…” Ellie wiped her mouth with the back of her paw. “So… Yeah, I come up to you like… this.”
As she approached the girl one year her junior, Ellie’s butterflies and funny feelings returned, and the feelings made her softening penis go rock solid again. Once in position, she placed both hands on the table by Manny’s sides, leaned over her, and gently kissed her.
Manny, in turn, reciprocated the kiss. It wasn’t as hot or as sloppy as Samantha’s french kissing, but Manny knew nothing about how that worked, and Ellie didn’t want to try pushing too far when she was already doing so many new things. 
The nine-year-old girl’s seven inch cock pushed against Manny’s pussy, and her virginal partner whimpered. After Ellie pushed a bit harder, the whimper turned to a groan, then the dick slid out of place and pushed up onto Manny’s tummy.
Manny broke her first kiss with a smile. Her face was flushed as red as a beet, but she had a big, giddy smile on her cheeks. 
“Mmm… Maybe I should… Hold onto the table, so you can push it in?”
Ellie obliged, and the two sloppily readjusted their privates to be touching tip-to-lips. The two braced themselves, pushed their parts together again, and with a lot of luck, Ellie managed to actually spread Manny’s lips apart and slid her tip inside of her.
Ellie froze up in pleasure and gawped. Her circumcised shaft’s tip had fully disappeared inside of Manny, and Manny in turn had gone from beet red and flustered to a darker shade of beet red and hurting.
“A-AH?! Ow?!? Holy butts, why does this HURT so bad?!” Manny groaned. 
Taylor and Samantha had come over and were watching Manny get penetrated with eager eyes and bated breath. Both of them were openly touching themselves at the display.
“I think that’s normal? Mommy says it gets easier after a few tries. Maybe push it in further?”
Ellie listened to Samantha and thrust her hips forward the slightest bit. The hot, cloying, crushing pressure of Manny’s virginal cunt clamping down on her cub cock was debilitating, and she felt that same feeling she’d had before with Samantha rising deep within her privates again.
Manny was not enjoying herself. “Nnnhg- no, no, ow ow ow ow ow! Hurts too much! Take it out!”
Ellie obliged her, and tried to pull her penis out of Manny’s pussy. The friction and sloppiness of her cunt had different plans, however, and the pulsing throbs of her cunt demanded she spill her nut inside. As she slid her penis out, her pulsating, pounding penis spurted a couple shots of jizz right up her vagina. As soon as she pulled out, the rest of her orgasm spurted all over Manny’s labia, giving her a nice cub crotch bukkake.
“Owwww…” Manny moaned. “Nnh… Ugh, that hurts.”
“Let me try, let me try.” Taylor pushed Manny’s shoulder. The older sister obliged and she pulled herself up with a wince.
Taylor pulled her pants down, just as her sister did, and laid down on the table in exactly the same spot. While the skinnier sister groaned and rubbed at the strange whitish gunk on her mound, Taylor reached down and spread her lips for Ellie.
“But won’t it hurt?” Ellie nervously asked.
“Manny’s a wimp! I can take it.” Taylor boasted, hefting up her chunkier, curvier hips for Ellie. 
With a shrug, Ellie picked up her slightly softened penis and put it against the lips of Taylor’s pussy. Before they’d even shared their first kiss, their privates had already started smooching.
Taylor gripped the edge of the table and braced herself for Ellie’s first thrust. Ellie, in turn, lined up her penis, which easily hardened back up to full mast, and she thrust in on her second attempt at penetration.
True to Manny’s word, Taylor’s body jolted with pain, and the chubby black cat let out a yelp.
“Ow! Oh my gosh, that REALLY hurts!” Taylor whined. “Uh, just… Kiss me, Ellie, and go slow. I can take it, I promise!”
Ellie leaned down, pressed her lips against Taylor’s, and enjoyed the warm, romantic moment between the girls. The two burgeoning cubs, kissing privates and properly losing their virginity together, rode out the wave of bliss and pain. 
While still holding the kiss, after a few seconds, Taylor bucked her hips against Ellie, and she nodded ever so slightly. Ellie, taking the hint, slowly started edging her shaft deeper into the girl.
Taylor tensed as Ellie’s penis pushed in through her well-developed vaginal canal, but the initial pain was by far the worst of it. Everything now was just a bit of a sting, and Taylor was too brave to be cowed by something as minor as that.
Inch by inch, Ellie’s pulsating, throbbing, cum-drooling shaft squelched deeper into Taylor’s body, until finally, the head of her penis ran up against the deepest depths of the prepubescent girl. Taylor tensed up at the new and alien sensation of someone being bottomed out in her deepest regions. Reluctantly, the two broke their first kiss, both with a smile on their face.
“See? T-Told you I could take it!” Taylor giggled through the pain, which quickly faded and was replaced with a warm sense of pleasure and satisfaction at being so full.
“Yeah! You’re amazing!” Samantha giggled, staring down at Taylor and Ellie’s crotches. “There’s almost no penis left!”
Ellie, who was on the verge of her third back to back to back orgasm, whined in delight and struggle. She was so, so close to making the goo spurt out, and she knew if she moved even the slightest bit, she’d start doing the thing that her body had done before and fill her privates up with gunk. But Ellie really wanted to make that special.
She pulled back just the slightest bit, whimpered in bliss as she felt her third ever orgasm start, and thrust forward. The tip of her cock butted up into the deepest parts of Taylor’s body, and her penis’ kissed Taylor’s cervix. As soon as her tip was sloppily making out with Taylor’s cervix, the spurt of cum shot up the shaft, and a dribble of her orgasm oozed right into Taylor’s baby-maker.
Taylor, in turn, felt her first orgasm come on from the repeated pulsating and throbbing and twitching of Ellie splitting her wide open for the first time. As Ellie’s cock drooled right into Taylor’s womb and she bred her new best friend, the two shared their second kiss.

A few months later, the four girls were making a little photo collage using a camera that Ellie had bought at a thrift store using her allowance. It was an old camera, and it printed real pictures. 
They were currently decorating a celebratory photo that all four had taken that June. It was a big day for Ellie, specifically: after she’d talked with her foster mom - she was very supportive of her - they’d agreed to put her on puberty blockers after her tenth birthday. The four had taken that picture that fateful June day that she’d taken her first dose of puberty blockers - the very same day they all attended their first ever pride parade.
Ellie was confidently showing her colours with a beautiful trans flag dress, and proudly holding up her puberty blockers for the camera. Taylor and Manny were both wearing matching lesbian pride flags as capes. Samantha had a pan pride shirt. And all three of the cis girls had big, gravid bellies from the litters that each were gestating.
Whether by coincidence or by some strange twist of fate, each of the three younger girls had gotten knocked up by Ellie, and she now was the proud ten-year-old mother to three growing litters of cute little kittens.
